Turn heavy PNG images into small HEIC files for iPhone, iPad and Mac, transparency included - for the web pick PNG to AVIF instead.
Want to check the result? Open it in the HEIC Viewer.
PNG keeps every pixel, which makes it heavy.
HEIC keeps the look - and the transparency - in a small fraction of the size, and Apple devices open it natively.
Screenshots and artwork for an Apple photo library are the typical use.
| PNG | HEIC | |
|---|---|---|
| Compression | Lossless (Deflate) | HEVC |
| Typical size | 100% | 10-30% |
| Transparency | Yes | Yes |
| Opens on | Everything | iPhone, iPad, Mac; Windows with extensions |
| Browsers | All | Safari only |
Going the other way? HEIC to PNG works for every device. Test files are in the PNG sample files.
Drop your PNG files into the box, keep quality 85 or pick a preset, and press Convert to HEIC. More than two files come as a ZIP.
Yes, briefly - browsers cannot write HEIC. Your browser sends one PNG copy over HTTPS, and our server deletes it the moment you download the result.
Photos and artwork often shrink by 70-90%; flat graphics save less.
Only with Keep EXIF on - by default they are removed. The page warns you when a photo contains a GPS location.
With the free HEIF and the HEVC extensions from the Microsoft Store. For sharing with Windows users, keep the PNG.
HEIF is the container; HEIC is HEIF with HEVC images inside - what iPhones save. Both open on Apple devices.
